Description

524854 Printed by A7 B7, Consumer Cooperative of Employees of Intellectual Property Bureau of the Ministry of Economic Affairs V. Field of Invention The invention relates to a method for manufacturing thin metal wires, especially cardwire, in which the selective Treated, especially drawn strands are drawn to a drawable state by a heat treatment process, then drawn, and then hardened and tempered to obtain predetermined mechanical properties; the invention also relates to a method for performing such Method device; a furnace device and a cooling device for the device. Description of the prior art Cards of pure metal and alloy steel cards produced by the methods described above, for example, are used to treat textile fibers in cards. For this purpose, the fine metal wire obtained in this way is further processed into a zigzag thread and, for example, is applied to a card clothing of a card. In order to process textile fibers, the card frame of the carding machine and its application device are set to rotate around the axis of the cylinder, so that the device can be cleaned by the fiber material being conveyed, in which the clothing is driven statically or oppositely Configuration and frame yarn interact. In this article, it must be ensured that a satisfactory treatment quality is obtained, that is, the uniform mechanical properties of the card lines used in all card clothing of the card. Furthermore, the mechanical properties of the card line must keep the total length of the zigzag lines applied to the card clothing at a often high level, because local defects in the card line can cause damage to the formed all-steel zigzag line device Instead, they must all be replaced. In modern high-performance cards, such damage results in high downtime and material loss. On the other hand, the total length of the helical and zigzag lines applied to the cylindrical gauze frame is hundreds of meters long in a modern high-performance card. Therefore, when the production of carding

Description of the invention (>) The method of machine wire must ensure that the final mechanical properties are constant over the entire length of several hundred meters. The following will explain a conventional method and the fine thread produced by the method that can meet these needs: In this regard, firstly a so-called wire rod is produced and drawn to the limit of narrowness. However, the drawn wire thus formed generally does not reach a sufficiently small cross-sectional area in a cross section perpendicular to the longitudinal direction. Therefore, the wire blank obtained from the first drawing process is traditionally heat-treated, so that it has a detailed structure that can be reprocessed and can be drawn again. During this heat treatment process, the wire embryo of the conventional method is initially heated to a temperature range of 800 to 100 ° C. The molecular structure of the steel used as the wire rod will be transformed into the structure of Vostian iron. . The wire is then quenched to a temperature range of 400 to 600 ° C and maintained at this temperature for a predetermined period of time. When using steel as a material for fine or carded wires, this procedure transforms the molecular structure into a Plei iron structure, which is characterized by superior cold work forming properties. After this transformation is completed, the wire is cooled to room temperature and subjected to hardening and tempering to obtain predetermined mechanical characteristics. To heat the wire to a temperature range of 800 to 1 000 ° C, conductive or inductive heating methods can be used. Due to the high energy costs and capital and financial costs of conductive or inductive heating furnaces, heating to 800 to 1,000 t is generally performed by electric or gas heating furnaces, so that the wire blank is guided to each of the furnaces. In the pipeline. This furnace has the additional benefit that the temperature of the wire section guided through the furnace can be maintained at a constant level better than conductive or inductive wire heating, and the Vostian iron structure obtained by this furnace is non-uniform.

The invention description (3 >) has a positive effect on the problem. In order to set the wire embryos to the required 400 to 600. (: Temperature range, which transforms the molecular structure into a boron iron structure, and keeps the wire embryo at this temperature. Traditionally, liquid feed is used. However, the use of liquid lead creates a problem because the wire embryo is in the liquid lead-air Oxidation at the interface cannot be prevented. Furthermore, the lead will take lead away when passing through the liquid lead bath. The lead that has been taken away must be removed from the wire and discarded. However, it is completely removed from the lead. Lead is almost impossible. Therefore, the lead remaining on the wire blank will have a negative effect on the further drawing process and eventually become a surface quality problem of the card line. Regarding the use of liquid lead to quench the wire blank and subsequently maintain it at These problems caused by temperatures from 4 0 to 6 0 ° C have been proposed in the past in a liquid bed. In a liquid bed, a flowable material, such as sand, is introduced as compressed air through a corresponding fluidization chamber The bottom of the wire is fluidized. When the wire embryo passes through the last layer of fluidized flowable material, the flowable material moves like a liquid in a fluidized state, so heat is quickly removed from the wire Due to the exudation of the embryo, the wire embryo is rapidly cooled to the temperature of the flowable material. However, when the layer of fluid material is fluidized, an unwanted oxide layer is generated on the wire embryo, although this oxide layer is traditionally Sand is partially removed because it is a flowable material, but it remains in the fluidization chamber. These so-called dirt particles have a negative effect on the quenching effect, so regular cleaning and periodic replacement of the flowable materials are required. In addition, in this method, the oxide particles that remain on the wire embryo must be chemically removed or corroded.

Description of the invention (bucket) The aforementioned problems arising from the use of fluidized beds When the flowable material is heated to a temperature range of 400 to 600 ° C to transform the molecular structure into a boron iron structure, 'the problem will be exacerbated because of these temperatures Facilitates the formation of an oxide layer '. In addition, in order to heat the flowable material, a gas burner is traditionally used, and the combustion products produced by it will be deposited on the strand. • From the use of liquid lead baths and fluidized beds, Except for the foreign material on the filaments, the oxide layer is called the dirt layer, and depending on the method used, the other lead residues are traditionally using so-called corrosion devices. Traditionally, they include corrosion tanks, which are generally filled with hydrogen Chloric acid or sulfuric acid, and many washing tanks that pass the strands in series in a sequential manner, and a drying device arranged downstream. In this way, return to the processable state, and the thread can be drawn, and then the traditional drawing method It is drawn to obtain the desired thread shape. Subsequently, the card line must still be hardened and tempered to obtain the predetermined mechanical characteristics. Especially the hardened and tempered are used to make the strength of the drawn thread. As high as possible, while achieving good rigidity and extensibility. For this purpose, a continuous hardening and tempering device has traditionally been used, in which the wire is first heated to a temperature between 800 and 1 000 t to obtain the structure of Vostian iron, and then quenched to obtain a molecular structure transformation Then, it is heated to a temperature range of 400 to 600 ° C to form a eutectoid from the molecular structure of Asada scattered iron, and finally cooled to a temperature of less than 60 ° C. In this article, in order to heat the drawn wire to a temperature of 800 to 100 ° C, an indirect heating method has traditionally been used, that is, an electric or gas heating furnace is used in which the wire is guided in a tube, And this paper size applies the Chinese National Standard (CNS) A4 specification (210'〆297mm) (Please read the precautions on the back firstΗ xi clothing-Γ page]-Order.-Line 524854 A7 B7 Intellectual Property of the Ministry of Economic Affairs Printed by the Bureau ’s Consumer Cooperatives. 5. Description of the Invention (s) Generally, inert gas such as nitrogen is filled to avoid oxidation. In the first step of the hardening and tempering process, the entire length of the furnace must be carefully checked for the predetermined line Temperature 'because only in this way can the required uniform mechanical properties be ensured over the entire length of the wire. • The purpose of the quenching step is to make the molecular structure as loose as possible for Asada. To ensure that the card line is required Mechanical properties, the formation of oxidized layers or dirt on the wire must be avoided at any cost. For this reason, the quenching zone of the conventional hardening and tempering device is connected to Vostian ironization in a gas-tight manner. Furnace. Attempts have been made to use a quenching medium other than oil, or a quenching procedure using water or air. However, with this method, the perfect results of the uniformity and fineness of the Asada loose iron structure cannot be obtained. As before As mentioned, in the second step of the hardening and tempering method, the temperature of the wire is heated to a temperature range of 400 to 600 t to form a eutectoid from the molecular structure of Asada scattered iron in the quenching step. This procedure also It is called annealing, and the required furnace device is called an annealing furnace. After the transformation is completed, the molecular structure includes an iron-based array and eutectoid embedding. In addition, heat or gas heating furnace can be used indirectly. In In this article, as described in the previous procedure, the wire is also guided in the tube and is generally filled with an inert gas such as nitrogen to avoid oxidation. In this hardening and tempering procedure, it is also necessary to ensure good temperature stability. To obtain the required uniform mechanical properties over the entire length of the wire. The wire is then cooled to a temperature of 60 ° C or less, which is traditionally performed indirectly in tubes with water flow.

Description of the invention (6 From the explanation of the above-mentioned conventional methods, it can be known that these methods require high equipment costs. Furthermore, they will produce materials that are harmful to the environment, such as liquid feed, sand and dirt particles, and acids used in decay equipment. , And the oil used for hardening during the hardening and tempering procedures. SUMMARY OF THE INVENTION Because of these prior art problems, an object of the present invention is to provide further development of the method described in the prior art, which can not only ensure the uniform mechanical properties of the card line produced, but also the method used to perform the method The capital investment cost of the device can be reduced, and the amount of environmentally harmful substances caused by performing the method can be reduced; and a device for performing the method is provided; and a furnace device and a cooling device used in the device. This object is solved by a method developed by the further development of the conventional method of producing fine wires, especially carding machine wires, which is characterized in that hardened and tempered drawn wires pass through at least one furnace that has been used to perform heat treatment procedures Device and / or cooling device. This further development is based on a very simple understanding that the heat treatment process is performed to obtain the drawable molecular structure line, which is affected by a temperature change curve, which is similar to the subsequent hardening and tempering procedures, and the temperature curve The difference and the adaptation to the specific conditions of other methods can be achieved by corresponding adjustments of the two processes' the heat treatment process and the hardening and tempering processes of the furnace device and / or the cooling device. In the text of the present invention, it is believed that the corresponding adjustment of the device used twice, especially the downtime of the device, can be kept to a minimum cost, and at least one device can be saved to make the overall cost-effective. This paper standard applies Chinese national standards ( CNS) A4 specification (210X297mm) I ---: ------ clothing II (Please read the notes on the back first n ► write this page) Order-line _ Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs and the Consumer Consumption Cooperative 524854 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 __B7 V. Invention Description (7) Higher manufacturing process. Furthermore, when saving at least one device, the space requirement of the device is reduced compared to conventional devices, and this also contributes to cost savings. Finally, when at least one device is used twice, the amount of environmentally harmful substances produced by performing the method of the present invention can be greatly reduced. This effect is particularly significant when at least one cooling device is used in the heat treatment process and the hardening and tempering process. As explained above in connection with the conventional method, when the heat treatment process is first heated in the first furnace unit to preferably about 8 A first temperature from 0 0 to 1 0 0 0 ° C, and then cooled by a first cooling device to a second temperature, preferably between the first temperature and room temperature, especially between about 4 0 to 6 0 (TC Temperature, and optionally maintained at this second temperature for a predetermined period of time, and then cooled to a temperature of about room temperature or slightly above room temperature by a second cooling device, it was found that the drawability of the obtained wire blank The molecular structure is particularly advantageous. In this article, the wire cooled to a second temperature of preferably about 400 to 600 ° C can also be maintained at this temperature for a predetermined time by the corresponding cooling device. Regarding the heat treatment process and the hardening and tempering process When the single unit was used twice as required, it was found to be particularly advantageous when the line was sold from the first cooling unit and maintained at the second temperature by the second furnace unit. The line could then be cooled by the first cooling unit The second temperature, and the wire is cooled in the hardening and tempering process, because the further heating of the wire blank in the hardening and tempering process can also be completed by the second furnace device. Using the method of the present invention, when used to perform heat treatment Only a single device is required for the procedure, that is, the first furnace device, the first cooling device, the second furnace device, or the second cooling device can also be used in the hardening and tempering process, which is very good (please read the back of the first (Notes-Installation-r this page)

The particularly large capital cost savings of the equipment used to implement the method of the present invention can be passed through the first furnace device, and the first cooling device ', the second furnace device, and the second cooling device on the hardening and tempering lines. Reached. It must be mentioned in this article that the embodiment of this preferred method is not applicable to the continuous manufacturing of carding lines, because between the heat treatment process and the hardening and tempering process, the necessary adjustment of a single device will first occur. However, this disadvantage is particularly acceptable for the manufacture of carding lines, because the required carding lines are traditionally below the maximum production capacity of the corresponding device, so the machine must be stopped during production according to the requirements of the carding line At this time, this stop neutral can be used to readjust a single device. Therefore, when the particularly preferred method of the present invention is performed, there will be no problem of additional cost of equipment shutdown. As explained above in connection with the conventional method, it is particularly advantageous when the wire is first heated to a temperature of about 800 to 1000 ° C and then quenched to room temperature when hardened and tempered. For this purpose, the first furnace device used to heat the wire blank to about 800 to 1,000 tons during the heat treatment process, and the first cooling device to be adjusted accordingly can also be used. In the further hardening and tempering phase, the wire is traditionally heated to a fourth predetermined temperature of about 400 to 60 Ot, and then cooled to room temperature or slightly less than 100 ° C above room temperature, preferably 60 ° C temperature. For this purpose, the second furnace unit and the second cooling unit can be used without any special adjustment. As explained above in connection with the explanation of the conventional method, it is particularly important to make the temperature in the corresponding furnace device constant over the entire length contained in the furnace when performing the hardening and tempering procedures. For this purpose, it was found that when the Chinese paper standard (CNS) A4 (210X297 mm) was applied in the -10-th paper size (please read the note boxing on the back ^^ write this page) Printed by the Employees 'Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 524854 A7 B7 Printed by the Consumers' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. The block is particularly advantageous when it is passed through by a corresponding channel and a spout in which the spouse can selectively pass. This heat distribution block can be constructed into a tube of higher quality, such as traditionally used, and has good thermal storage properties, so that temperature fluctuations in the furnace device can be buffered ', so there is no longer a line temperature effect or line temperature in the furnace process. In addition, the use of the heat distribution block passed by the line can use a gas furnace with a small furnace chamber, while still ensuring a constant temperature distribution, because local temperature spikes caused by the gas burner, even in small furnaces In the room, even when the heat distribution block of relatively high quality is used, it can be evenly distributed, and no longer reaches the line passing through the heat distribution block. As can be seen from the above description of the particularly preferred embodiment of the method of the present invention, the furnace device used by the present invention to perform the method has at least one furnace chamber for accommodating at least one line section, and is characterized in that a cable is arranged in the furnace chamber. In the area, a heat distribution block is configured to uniformly heat the wire portion accommodated in the furnace chamber. In this context, the furnace chamber conveniently includes at least one line inlet and at least one line outlet spaced from each other and can be operated continuously. In order to uniformly heat the wire portion accommodated in the furnace chamber, it may be more desirable when the heat distribution block is passed through at least one passage containing the wire portion, or by a tube that closely surrounds the wire portion. In a particularly preferred embodiment of the present invention, the furnace device of the present invention is designed to simultaneously heat a plurality of wire sections, wherein the heat distribution block is extended by a plurality of parallel, each of which passes through a passage containing a wire section. In this article, the heating of the wire portion of the heat distribution block can be achieved by heating the heat distribution block from the outside, preferably at least one through a furnace chamber -1 1-This paper size applies to Chinese National Standard (CNS) Α4 Specifications (210X297 mm)

When using this furnace device, when at least one channel for accommodating the wire part is sealed in an airtight manner with respect to the heated environment of the heat distribution block, and is preferably filled with an inert gas such as nitrogen, in the furnace chamber Dirt on the wire portion to be heated and deposition of combustion products on the wire surface can be prevented. It has been found to be particularly advantageous when the heat distribution block includes at least partially semiconducting materials, as such materials have a good thermal capacity and a perfect thermal conductivity in the relevant temperature range of 400 to 1000 ° c, And at the same time have minimal weight. In this paper, it has been found that silicon carbide is particularly advantageous when it is used as a semiconductor material because it has particularly good thermal properties and is particularly light weight. As explained above in connection with the manufacturing process of the conventional line, the first and / or second cooling device may be a fluidized chamber with a layer of fluidized material, e.g., a fluidized chamber 'line of sand may be cooled through it. In order to prevent the generation of a dirt layer on the line passing through the fluidization chamber, it has been found to be particularly advantageous when the flowable material is fluidized with an inert gas, such as nitrogen or a rare gas, etc., which is introduced into the fluidization chamber. In the last-mentioned method, when the inert gas introduced into the fluidization chamber is reintroduced after being removed from the fluidization chamber, the operating costs associated with carrying out the method of the present invention can be kept low. In addition, the 'inert gas used to fluidize the flowable material in the fluidization chamber' may produce a considerable reduction in the amount of harmful substances to the environment during the production line, because the generation of dirt particles is prevented, otherwise it must be replaced frequently. Flowing material. Moreover, the flowable material is fluidized in the fluidization chamber. 1-2 2-This paper size is in accordance with China National Standard (CNS) A4 (210X297 mm).

Invention The use of inert gas (H) also opens up the possibility of completely eliminating the corrosion device. 'Otherwise, it is necessary to use the corrosion device to process the line from heat treatment to the drawable state.' Because the line is cooled to the second temperature, no Oxides are generated on the surface of the wire. Therefore, the environmentally harmful substances produced by performing the method of the present invention can be further reduced because the acid used in the corrosion device in the traditional method is no longer needed. Furthermore, when an inert gas is used to make it flowable When the material is fluidized, the fluidization chamber can be used for hardening in the hardening and tempering process, because in this method, for the sake of quality, at any cost, the dirt on the line must be prevented during the hardening and tempering process. It can be reliably prevented. In this way, the environmentally harmful substances produced by performing the method of the present invention can be further reduced, because it is used to harden and temper the wire. The oil used for quenching is no longer needed. In a particularly preferred embodiment of the present invention, one and the same fluidization chamber is used in the heat treatment process, and the hardening and tempering processes to obtain the drawable molecular structure. In this paper, when a fluidizing chamber is used to cool a flowable material during a heat treatment process, the flowable material is heated to a second predetermined temperature, which is traditionally more appropriate at a temperature of about 400 to 600 ° C. Although As in the prior art, this heating can directly heat the flowable material and the gas used to fluidize the flowable material using a gas burner. It has been found to be particularly advantageous when electromagnetic waves are emitted to the fluidization chamber to heat the flowable material, because In this way, due to the use of the gas burner, the deposition of combustion products' on the surface of the wire can be prevented, and the corrosion device used to treat the wire which has been transformed to the drawable state by the heat treatment process can be completely eliminated. • 1 3-This paper size is in accordance with Chinese National Standard (CNS) A4 (21〇 × 297 mm) (Please read the precautions on the back-Pack-^ write this page) Ordered by the Intellectual Property Bureau of the Ministry of Economic Affairs, printed by the Consumer Cooperative 524854 A7 B7 V.

This embodiment of the present invention has an advantage that in addition to the electromagnetic waves emitted by the heating tube, when the heating tube is arranged in the region of the fluidized flowable material layer, the flowable material and the heating tube Direct contact can also be produced. The heating tube can be, for example, an electric heating method. However, in order to obtain particularly high efficiency, it has been found that it is particularly advantageous when the heating tube is a hollow tube and is heated internally by a gas burner, of which The interior of the tube is spaced from the other parts of the fluidization chamber in an airtight manner. Additionally or alternatively, the flowable material may be heated by electromagnetic waves in the form of microwaves radiating to the fluidization chamber. In this context, an element such as a klys tr on, which corresponds to a microwave radiation device used to generate microwaves, may be arranged in the region of the fluidization chamber wall, and in this way, a flowable material is generated Waste heat caused by microwaves is reheated.

Description of the Invention ($) In the bottom area of the corporatization chamber 2 10, there is a device for introducing an inert gas into the fluidization chamber. The inert gas introduced in this way, the flowable material contained in the fluidization chamber, such as sand, can be fluidized so that a liquid fluidized layer is formed, and the line to be cooled is introduced through the liquid fluidized layer. Inert gases such as nitrogen, rare gases, etc., which are thus introduced into the fluidization chamber 2 10, are removed from the fluidization chamber 210 and returned to the introduction device 220. Above the introduction device 220, the fluidization chamber 210 is penetrated by a heating pipe 240 extending perpendicular to the line passing direction. This heating tube 240 forms a hollow tube, and a gas burner 242 is enclosed inside, wherein the inside of the heating tube 240 is air-tight and is separated from other parts of the fluidization chamber 210. In this manner, the fluidized sand fluidized by the inert gas introduced through the introduction device 220 in the fluidization chamber 210 can be heated to a predetermined temperature of about 500 ° C during the heat treatment process, and fluidized. The inert gas in the chamber 2 10 will not be contaminated by the combustion products, while at the same time ensuring that the lines passing through the fluidization chamber 2 10 will not be oxidized, because the fluidization is performed in an inert gas environment. The exhaust gas of the gas burner is removed by the suction device 242 and conducted away. The invention is not limited to the description of the embodiments with reference to the drawings. Conversely, the flowable material in the fluidization chamber 2 10 can also be heated by microwave stirring. One of the corresponding microwave generating elements, such as a klystron (k 1 ystr ο η), is arranged in the fluidization chamber 2 1 0 In the region of the side walls, the flowable material can thus be heated and, on the other hand, cooled by the flowable material. Furthermore, the device of the present invention can also be adjusted so that the temperature variation curve deviating from the temperature curve of Fig. 1 is used, for example, using high alloy steel as the wire material to be produced.
